Hinge device for doors, shutters and the like

Abstract

A hinge device includes a first fixed tubular half-shell having a working chamber defining a longitudinal axis, a second tubular half-shell rotatable about the longitudinal axis, a pivot rotating unitarily with the latter which includes a single pass-through actuating member having a helical shape, a plunger member slidable along the longitudinal axis, and a tubular bushing having a pair of guide cam slots. A pin inserted within the pass-through actuating member is provided to allow the mutual engagement of the pivot and the bushing. The first tubular half-shell includes an end portion susceptible to rotatably support the pivot, the second tubular half-shell and the bushing are coaxially coupled to each other, and the bushing and the first tubular half-shell are mutually unitarily coupled.

Description

FIELD OF INVENTION[0001]The present invention is generally applicable to the technical field of the closing and / or control hinges for doors, shutters or like closing elements, and particularly relates to a hinge device for rotatably moving and / or controlling during closing and / or opening a closing element, such as a door, a shutter or the like, anchored to a stationary support structure, such as a wall or a frame.BACKGROUND OF THE INVENTION[0002]As known, hinges generally include a movable member, usually fixed to a door, a shutter or the like, pivoted onto a fixed member, usually fixed to the support frame thereof, or to a wall and / or to the floor.[0003]From documents U.S. Pat. No. 7,305,797, EP1997994 and US2004 / 206007 hinges are known wherein the action of the closing means that ensure the return of the door in the closed position is not damped. From document EP0407150 is known a door closer which includes hydraulic damping means for damping the action of the closing means.[0004]...

AI Technical Summary

Benefits of technology

The present invention provides a hinge device that has high functionality, simple construction and low cost. It allows for a quick and simple adjustment of the opening and closing angle of the doors to which it is attached. Additionally, it is small in size and can automatically close doors that are heavy.

Problems solved by technology

All these known devices are more or less bulky, and consequently they have an unpleasant aesthetic appeal.

Moreover, they do not allow for adjustment of the closing speed and / or of the latch action of the door, or in any case they do not allow a simple and quick adjustment.

Further, these known devices have a large number of construction parts, being both difficult to manufacture and relatively expensive, and requiring frequent maintenance.
